LOCATION & INSTALLATION GUIDELINES
n Locate the machine on a solid and level surface so that engine and pump crankcase oil lubricate components properly.
Avoid areas where water can build up in the working area. Possible injury can occur caused by the surface becoming
slippery from water build up.
n Locate the machine in a well-ventilated area and away from flammable materials or fumes. Be sure ventilation warnings
are observed. Keep pressure washer at least 18” away from flamable materials.
n Locate the machine so the operator has easy access to the pressure washer and its controls. Locate the machine so that
it is protected from external damage.
n Confer with local gas company, and with proper municipal officials regarding any specific code or regulations governing
this installation. Installation must conform with all local codes prior to operation of machine.
n A draft diverter hood must be installed and vented to the outside.
n Check gas union located under burner ring prior to operation. Soap test gas pipe fittings for leaks once pressurized.
n To prevent damage and excessive hose wear, locate the pressure washer so that the hose does not cross traffic areas
n The gas line should be a separate supply direct from the meter to the burner. New pipe is recommended to be
used and located so that a minimum amount of work will be required in future servicing. The piping should be
so installed as to be durable, substantial and gas tight. It should be clear and free from cutting burrs and defects
in structure of threading. Cast iron fittings or aluminum tubing should not be used for the main gas circuit. Joint
compounds (pipe dope) should be used sparingly on male threads only and be approved for all gases.
n Venting: A vented draft diverter hood should be used with all indoor installations. Poor draft will cause the
machine to soot and not operate efficiently. Positioning of the machine should be in such a manner so that the
stack is as straight as possible and have suffecient height to eliminate downdraft.

n
Protective eye wear is advised during operation of the HotBox
n
Position HotBox on level surface away from outside influences such as rain, strong
winds, open flame, or freezing temperatures
n
Check that the HotBox thermostat dial is in the “OFF” position.
n
Connect a hose from the pump outlet on the pressure washer to the bottom of the coil on the HotBox.
n
Attach hose with wand to top of coil on the HotBox
n
Install desired water nozzle at the end of wand, making sure it is clear of any obstructions.
n
Star t "Cold Water" pressure washer. Open the trigger gun while firmly gripping the wand
assembly. Grasp the grip on the wand with one hand and the trigger gun with the other.
n

HEAT EXCHANGER COIL PRECAUTIONS
n
n
High mineral content in water may require a water softener installation.
Do not permit acidic, caustic or abrasive fluids to be pumped through system.
FAILURE TO MAINTAIN HEAT EXCHANGER COIL MAY
RESULT IN A STEAM EXPLOSION WHICH MAY CAUSE
SERIOUS INJURY OR DEATH.
HEAT EXCHANGER COIL MAINTENANCE
n Hard water conditions may eventually cause clogging in the heat exchanger coil if left unattended.
Scale deposits will compromise the heating efficiency and produce an unsafe condition over time.
It may be necessary to descale coil.
n
Scale buildup from certain detergents may eventually clog up the heat exchanger coil causing an
unsafe condition. Use only recommended detergents for better cleaning efficiency.
n
Black carbon deposits that collect on the outside wall of the heat exchanger coil may be a result of
using a poor grade of fuel or improper burner operation. Heating fuel should be void of water and
sediments to eliminate the possibility of sooting and compromising the efficiency of the coil.
